Guide to Installation and useof keil Vision2 Software


2/40

Install from:

keil7_setup setup setup.exe


3/40

Select Full Version


4/40

Enter Serial Number

K1RIP-M2192-KO14E


5/40

Browse foradd-ons Path


6/40

Path is: keil7_setup addon c51 addon


7/40

Check () Install Security key driver Next


8/40

Now setup is complete and keil Vision 2 isInstalled on your PC.

Run the software from the short-cut on your

desktop.A project named Hello containing file HELLO.c

will be opened automatically as you run thesoftware for the first time.

Close this project from:Project menu Close Project


9/40

Close Project Hello


10/40

Now you have Keil Vision IDE


11/40

To Create your own Project go to:

Project Menu New Project


12/40

Create your own Project after creating newproject folder/directory at your desired location

Your Project Name(will automatically get the extension .uv2)

Your Project / Working Directory Use to set location and create new folder


13/40

Now Save the project by clicking on the Savebutton

As you click on the Save button,a device selection windowwill automatically appear

as shown on the next slide


14/40

Target Device (The microcontroller we will use) Selection.Expand (Click +) on Atmel


15/40

Select: Atmel 89C51 OK


16/40

Now create a New File from the short-cut buttonor from: File menu New


17/40

A New Text* file will be created which will be oursource code file in the future


18/40

Now write the following simple c program in the text file

#include /* special function register declar/* for the intended 8051 derivative */

void main (void)

{while(1) /*------------------------------------------------

Note that an embedded program never exits (becausethere is no operating system to return to).It must loop and execute forever. So, "while(1)" loop.------------------------------------------------*/

{

P0=0xaa; // Sends High andL

ow on alternate Pins of Port 0P0=0x55; // Sends High and Low on Port 0 in reverse order}

}


19/40

Program is written. All text between /* and */ or followed by // isnot part of the code and is just comments / documentation


20/40

Now save the file from: File Menu Save as File NameNote that the file name must be written with dot c (.c) extension


21/40

Note:In case the Program is written in assembly language,

the file must be saved with dot asm (.asm) extension.Also note that the moment we save the Text* file (with.c or .asm extension), the code in the file gets a

standard colour scheme


22/40

Now click on + sign of folder Target 1 shown inProject Window on the left side of IDE

Project Window

Click toOpen


23/40

A Source Group folder will appear containing nosource code file as shown


24/40

We have created a project named First and alsowritten a program in C language (LEDs.c in this

example) and saved it with dot c extension, but bothProject and source code files exist separately. As

shown by empty Source Group folder.So, we have to add source code file into the Project


25/40

Right Click on: Source Group Click: Add files to Group Source Group 1

RightClick


26/40

A window showing source code files will appear.Select , Add and Close.


27/40

The added file will be shown in Source Group folderin Project Window

Click to Open


28/40

Now go to Project Menu Options for Target Target 1or simply right click Target 1 in Project Window

Options for Target Target 1

Right Click


29/40

In Options forTarget Window, underTargetTaga) Edit Xtals Freq. to 11.0592MHz (replacing 24.0)b) and Code Rom Size to Small program 2K, or less


30/40

Similarly, underOutput Tag Check () theCreate Hex File Check Button

Click toCheck


31/40

Now Project is complete with all necessary settingsand is to be built (Compiling and Linking Process)

So, Project Build Project or Use Short-cut


32/40

See the result ofBuild target command in the OutputWindow

Output Window

Successful building of Project andCreation of Hex file


33/40

Creating hex file.line in the command windowshows that a hex file of the same name as that of the

project has been successfully created which can nowbe burnt into the microcontroller.The default location of the hex file is same as that

of the project i.e. our own created directory.


34/40

Keil Vision Debugger

The Debugger of the keil software is used for software simulation

of the code before loading / burning it into the targetmicrocontroller


35/40

Start Debugger from: Debug Menu Start / Stop Debug sessionor from short-cut on the debug tool bar


36/40

Now to view Hardware/Ports status (Port 0 in our case), go toPeripherals I/O Ports Port 0


37/40

Parallel Port 0window will appear showing the Dataon the Port


38/40

We can simulate our code in 2 modes1) Step by step execution (Debug Step over or F10)

(2) Free Running mode (Debug Go or F5)


39/40

For step-by-step execution select source code windowby left clicking any where on the window and thenuse function key F10 to debug / simulate the code


40/40

For Free running mode (Go Command), dont forgetto enable Periodic Window Update in View Menu
